WRNK series Armored thermocouple 、耐高壓

、熱響應(yīng)時(shí)間快和堅(jiān)固耐用等許多優(yōu)點(diǎn)

，它和工業(yè)用裝配式熱電偶一樣

，作為測(cè)量溫度的變送器

，通常和顯示儀表、記錄儀表和電子調(diào)節(jié)器配套使用

，同時(shí)亦可作為裝配式熱電偶的感溫元件

。">Has many advantages of high pressure resistance, bending, thermal response time fast and durable, it and industrial assembly type thermocouple, as a measurement of the temperature transmitter, and usually display instrument and record instrument and electronic regulator supporting the use, at the same time as the temperature sensing element assembly type thermocouple.

、蒸汽和氣體介質(zhì)以及固體表面的溫度。">It can directly measure a kind of production process from the 0~1300 temperature range of liquid, steam and gas solids and surface temperature.

、結(jié)構(gòu)原理：">Two, structure principle:

，兩種不同成份的導(dǎo)體兩端經(jīng)焊接，形成回路

，直接測(cè)溫端叫工作端

，接線端子端叫冷端，也稱參比端

。">WRNK series of <strong> armored thermocouple</strong> works, two different components of the conductor ends by welding, forming a loop direct temperature measuring end called the working end, the terminal end is called the cold end, also called the reference terminal. ，就會(huì)在回路中產(chǎn)生熱電流，接上顯示儀表

，儀表上就會(huì)指示出熱電偶所產(chǎn)生的熱電動(dòng)勢(shì)的對(duì)應(yīng)溫度值

。">When the temperature difference between the working end and the reference end, will produce thermal current in the circuit, connected to display instrument, the instrument will indicate the corresponding temperature of the thermocouple electromotive force generated by the value of the.

，和熱電極的長(zhǎng)度

、直徑無關(guān)。">The thermocouple electromotive force will increase with the increase of temperature measuring end, only the size of Thermal EMF and thermocouple conductor material and the temperature difference between the two ends, and the length and diameter of independent power pole.

，是由導(dǎo)體

、高絕緣氧化鎂、外套 1Cr18Ni9Ti不銹鋼保護(hù)管

，經(jīng)多次一體拉制而成

。">WRNK series of <strong> armored thermocouple</strong> structure, is composed of a conductor, high insulation, magnesium oxide coat 1Cr18Ni9Ti stainless steel protective tube, one drawn by many. ，并配以各種安裝固定裝置組成

。">The product is mainly composed of armored thermocouple junction box, terminal and sheathed thermocouple components of the basic structure, and with various fixed device. Armored thermocouple type insulation shell and then two.

、主要特點(diǎn)：">Three, main features:

，減小動(dòng)態(tài)誤差；">The thermal response time, reduce the dynamic error;

；">Flexible installation;

；">Large measuring range;

；">High mechanical strength, good pressure resistance;

、技術(shù)參數(shù)：">Four, technical parameters:

Product executive standard

IEC584

IEC1515

GB/T16839-1997

JB/T5582-91

Nominal pressure thermocouple: generally refers to the static outer protective tube can withstand working temperature and pressure rupture.

Thermocouple: minimum insertion depth should be not less than 8-10 times the diameter of the protective sleeve (Frederick product exception)

，相對(duì)濕度＜80％時(shí)絕緣電阻≥5兆歐（電壓100V）

。">Insulation resistance: when the ambient air temperature is 15-35 DEG C, relative humidity is less than 80% when the insulation resistance is more than 5 megohm (voltage 100V). ，絕緣電阻≥0.5兆歐（電壓100V）">With the splash proof junction box of the thermocouple, when the relative temperature is 93 + 3 DEG C, the insulation resistance of more than 500 billion euro (voltage 100V)

，其熱電極（包括雙支式）與保護(hù)管以及雙支熱電極之間的絕緣電阻（按每米計(jì)）應(yīng)大于下表規(guī)定的值

。">The insulation resistance of high temperature thermocouples under high temperature, the thermal electrode (including double type) and the insulation resistance between protection tube and double heat electrode (per meter) should be greater than the value specified under the table.

，試驗(yàn)電壓為500±50V（直流）電極與外套管之間的絕緣電阻>1000Ω.m

。">Armored thermocouple at ambient temperature for 20 + 15 ~ C, the relative humidity is not more than 80%, the test voltage is 500 + 50V (DC) insulation >1000 resistor between.M electrode and outer tube.
